Polarizing film, image display apparatus, and method of producing polarizing film

Abstract

A polarizing film according to an embodiment of the present invention includes a polarizer and a support. The support is formed on at least one surface of the polarizer. The support has a pattern structure. The method of producing a polarizing film includes a step of forming a pattern of a resin material on at least one surface of a polarizer; and curing the resin material to provide a support having a pattern structure.

What is claimed is: 
     
         1 . A polarizing film, comprising:
 a polarizer; and   a support formed on at least one surface of the polarizer,   wherein the support has a pattern structure.   
     
     
         2 . The polarizing film according to  claim 1 , wherein the polarizer has a thickness of 15 μm or less. 
     
     
         3 . The polarizing film according to  claim 1 , wherein the support has at least one structure selected from the group consisting of a honeycomb structure, a truss structure, a rigid-frame structure, a stripe structure, and a circle structure. 
     
     
         4 . The polarizing film according to  claim 1 , wherein the support has a thickness of from 1 μm to 15 μm. 
     
     
         5 . The polarizing film according to  claim 1 , wherein the support has a width in a plan view of from 500 μm to 3,000 μm. 
     
     
         6 . The polarizing film according to  claim 1 , wherein the support has optical isotropy. 
     
     
         7 . The polarizing film according to  claim 1 , further comprising, on the one surface of the polarizer, an embedding resin layer configured to embed the support therein. 
     
     
         8 . The polarizing film according to  claim 1 , wherein the support has a compressive modulus of elasticity at 23° C. of from 0.01 GPa to 8.0 GPa. 
     
     
         9 . An image display apparatus, comprising the polarizing film of  claim 1 . 
     
     
         10 . A method of producing a polarizing film, comprising:
 forming a pattern of a resin material on at least one surface of a polarizer; and   curing the resin material to provide a support having a pattern structure.
